Gulf Stream itself in danger of disruption.

Arctic melt leading to weakest Gulf Stream in a 1,000 years
Gulf Stream water currents in the Atlantic Ocean have slowed to the weakest in as long as 1,000 years, threatening shifts in US and European weather, as well as coastal sea levels including in New York and Boston.

The loss of Arctic sea ice as a result of global warming could have dramatic and potentially catastrophic effects on the climate of much of the northern hemisphere, according to a new report.

Scientists at Yale University and the University of Southampton recently demonstrated that the ongoing loss of sea ice is actively changing one of Earth’s main systems for transporting water — the Atlantic Meridional Overturning Circulation (AMOC).

To put it simply, AMOC circulates cold, dense water from the north Atlantic southward and warm, salty water from the tropical Atlantic northward. This system, which includes the Gulf Stream, plays a major role in maintaining the global climate, and its deterioration could have a dramatic impact.

“We have shown that this contraction of Arctic sea ice leads over the course of several decades to the weakening of the Atlantic Meridional Overturning Circulation,”

The shutting off of the Gulf Stream will be a catastrophic climatic event. Here's what would happen;

Arctic ice melt will produce massive quantities of cold water which will sink and flow south .
These masses of cold water will encounter the warm Gulf Stream currents flowing north and , literally, block their northern progress.
The far denser cold water will firstly flow beneath the warm stream until it just ain't warm no more, girls and boys.

We've been warned about this for over fifty years- and now it appears imminent.

The Atlantic overturning is driven by what the scientists call deep convection, triggered by the differences in the density of the ocean water: Warm and salty water moves from the south to the north where it cools down and thus gets denser. When it is heavy enough the water sinks to deeper ocean layers and flows back to the south.
Global warming disturbs this mechanism: Increased rainfall and enhanced melting of the Greenland Ice Sheet add fresh water to the surface ocean. This reduces the salinity and thus the density of the water, inhibiting the sinking and thus weakening the flow of the AMOC.
Its weakening has also been linked to a unique substantial cooling of the northern Atlantic over the past hundred years. This so-called ‘cold blob’ was predicted by climate models as a result of a weakening AMOC, which transports less heat into this region.

Current Atlantic Meridional Overturning Circulation weakest in last millennium

Abstract
The Atlantic Meridional Overturning Circulation (AMOC)—one of Earth’s major ocean circulation systems—redistributes heat on our planet and has a major impact on climate. Here, we compare a variety of published proxy records to reconstruct the evolution of the AMOC since about AD 400. A fairly consistent picture of the AMOC emerges: after a long and relatively stable period, there was an initial weakening starting in the nineteenth century, followed by a second, more rapid, decline in the mid-twentieth century, leading to the weakest state of the AMOC occurring in recent decades.

It seems to me that the ONLY sane approach to combating global warming- and its inherent climate changes- is to err on the side of caution, despite the raging of self-obsessed capitalist dumbasses.
 
Remember- they WANT it to be ' too late ' . Inhibiting climate action is part of their insane agenda.
